Application filed August as, 1925. Serial No. 52,562.

This invention relates generally to mobile units, that is to say, units adapted to some. useful purpose while capable of propulsion v under their own power from place to place,

in contradistinction to those now commonly An object of this invention is to provide;

an attachment frame for rigid connection to ia motive unitsuch as a tractor for ex- I place to place.

amplewh ich is so designed as to'ensure a non-vibratory support for the util ty adapted for operation by the motive unit when 'not'.

engaged in propulsion or travelling from Another object of' this inventionv is the provision of an attachment frame component characterized by great strength and ease of tractors into mobile units including one or more utilities adapted for operation thereconnection or disconnection to thecrank case and rear axle housings of standard types of tractors whereby said tractors are adapted to the same with maximum economy.

A further object of this invention as the cheap and economical conversion of standard Vt ith the foregoing and other objects in view, which will be apparent fromthe following description,

sheets of drawings, and circumscribed as tosubject-matter and scope by the appended claims.

In the drawings p Figure 1is a top plan vlew of my novel attachment frame as adapted to a standard type of tractor, a portion whereofis frag mentarily shown, while the associated. utility is indicated diagrammatically by dot-anddash outline so as not to-confuse the illustration.-

Figure II-is aside elevation of the pre ceding figure.-

include a work utility or the like and operate this invention essentially consists of-the matters hereinafter set forth, typically exemplified in the accompanying- PHIA, PENNSYLVANIA, A, CORPORATION- OF Figure III-, is a persp'ective viewof. the attachment frame with minor parts broken away for the sake ofclearness; and,

Figure IV-is a fragmentary detail-of a portion of the attachment frame, later on fully explained.

For the sake of practical explanation asto one convenient application of thepresent' 1nvention I have electedby way of example 'only-to-describe the'same as adapted to a mobile compressor unit, but it is to be distinctly understood that I am in no sense v limited thereby. I

Referring more specifically to the drawings, on which like reference numerals are appliedto corresponding arts in all the views, it' will be observed t at the rear portion of'a standard type. of tractor-is comprehensively designated 5, while the numeral 6 indicates the rear axle. housings. '7 is the steering wheel, 8 the operators seat, 9 the 1' foot brake, 10 the gear shift, 11 the clutch control, and 12 the lever which connects or disconnects the compressor 13, as later on explained. The rear wheels ofi the tractor-5, are designated 14 while a portion o'fthe fuel tank is shown at 15. As the foregoing parts are old and well known, further explanation thereof is deemed unnecessary herein, and they are but briefly enumerated; as essential toa' full comprehension of my invention, now to be described in detail.

As best appreciated from Figure-III, it willbe noted'that, in the main, this invention comprises a" :framework attachment,

comprehensively designated 16, and com-.

prising opposed side units 17 18, detachably connected at their rear ends by a transverse member 19. Each side unit 17, 18, it will be seen, consists, conveniently though not es sentially, of a standard I-beam or longitudi-- v nal 20, that is cut away and shaped as later on fully plained, with a sub-plate 21 welded to t e fore basalflanges thereof at I 22, as well as rigidly united by spot weld ings23,-through said basal flanges at each side of the web thereof. These sub-plates 21,

it is to, be particularly remarked, thus be come incorporated base flanges of the I- beams 20 and they are configured to snugly conform to the crank case 24 of the tractor 5. 1

In addition to the foregoing, the sub-plates 21 are provided with a series of 11019525 adjacent their-inner edges for substitute bolts the ordi- 26e-'-Fi ure Iwhich pass throu h case. and

nary ange holes of the era cover, as will be well understood by anyone acquainted with tractors. Furthermore, the type of tractor'illustrated, is provided on the rear axle' housings 6 with; vertical oflsets 27--Fi-gure IIand these I'bore and tap to receive studs' 28 passed through holes ,29-

Figure III- in the aforesaid sub-plates '21. Thus it will be seen that the side units 17 18 are-rigidly supported and connected to the tractor 5 1na manner effectively precluding any tendency to lateral or other displacement while affording rearwardly extendlng stable support for the compressor 13. In order to rigidly brace the side units 17 18 a ainst vertical deflection, I weld oblique- 1y isposed angles or channels 30 to the lower rearflanges of the I'-beams 20 at 31;

said angles or channels 30 being cutaway and shaped at their forward ends to provide eye-pieces 32 which are bolted or otherwise'secured at 33 to the flange of the juxtaositioned axle housing 6, as clearly shown in Figure II. Attention is also directed to the-fact that I additionally unite the brace members 30 rigidly to the base flanges of the I-beams' 20 by spot weldings 3 1Figure III.

Referring now to the rear transverse member 19, the same is conveniently cut from a standard channel section to snugly seat at 35Fi ure' III-{between the upper and lower' anges of the I-beams 20, and it has angle clips 36Figure IVwelded thereto I by means of which it is secured in place between the side units'17, 18 through the 'me-. dium of bolts 37. Thus it will be readily seen that the side units 17 18 are-trans- Lverselybraced in a rigid manner at their -rear ends, and thereby aflord a. secure bearing for the compressor 13 which is mounted thereon and secured in place by bolts 38- Figure II' passing through holes 39 in-the.

to flan es of the I-beams 20 Figure III.

O vious maybe tted at intervals intermediate the side units 17, 18 where deemednecessary.

As the specific form of unit illustrated in- -volves a storage tank 40 for the compressed air produced y the compressor 13, I afford chock spacerstherefor in the form of transversely disposed angle irons 41, 42 of suflicient length. These angle irons 41, 42, it will 'be seen, extend beyond the side lines of the v integrally welded at 43 to the top flange of attachment frame '16, and' the former 41jis the transverse member 19, while the latter has an 1e clip 44 welded thereto with, ro-' vision or bolting connection 45 to the a oresaid I-beams 20, as will be readily understood. The storage tankcis secured to the chock pacers 5H, 42 by rem'ovable straps 46 and bo ts 47, in'the well knownmanner;

additional transverse channels" ber detachably eonnec From the foregoing it will be seen that the attachment frame 16 extends rearwardly from the tractor 5, and that it forms and constitutes a rigid support for the compressor 13 which is. operated by a direct rive connecting shaft 48Figure IIfrom the tractor transmission, and that it can be connected 1 or disconnected from operation therefrom by the lever 12, aforesaid.

From the foregoing description, taken in connection with the-accompanying drawings, the construction and manner-of mounting or dismantling my novel attachment frame .will be well understood without further detailed explanation,- while its ready adaptability for compact shipment is selfeviderit.

Furthermore, changes inftheform, proportions andminor details, obviously, may be made within the scope of my invention with-- out do arting from the spirit or sacrificing any 0 the advantages thereof," particularly in so far as the cutting away of the Lbeam '-20 flanges is concerned to conform to different types. of prime movers, as well as tov accomodate other utilities than that specifically illustrated. Accordingly the rightis hereby reserved to, make all such reasonable changes as are fairly circumscribed by the scope of the subjoined claims.
